interesting baby galaxy pics.–BenTracing the growth of Milky Way-like galaxiesThis composite image shows examples of galaxies similar to our Milky Way at various stages of construction over a time span of 11 billion years.The galaxies are arranged according to time. Those on the left reside nearby, while those at the far right existed when the cosmos was about 2 billion years old. The bluish glow from young stars dominates the colour of the galaxies on the right. The galaxies on the left are redder from the glow of older stellar populations. http://www.spacetelescope.org/images/opo1345a/
